Results of two specific gravity 20 °C/20 °C measurements: 1.610 and 1.643, mean 1.626; mean density 1.623 g/mL.
The density of the purified substance was also determined, and the result was 1.635 g/mL at 20 °C.
Description of key information
relative density at 20 °C to water at 4 °C: 1.623 (OECD 109, EU A.3, OPPTS 830.7300)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.632
Additional information
The relative density of the test substance was determined using pycnometer method. The value of 1.635 was obtained for the relative density of the purified grade of the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
